摘要:
A coating composition for application to primed metal substrates as a topcoat is disclosed. The coating composition is especially useful on metal closures for vacuum-packed food products. The coating composition is free of a halide-containing vinyl polymer and comprises: (a) an acrylate co-polymer having pendant hydroxy groups, (b) a hydroxy-terminated polyester, (c) a crosslinker, and (d) a nonaqueous carrier.

摘要:
A device for closing a food container that includes a barrier substrate that sufficiently inhibits oxygen and moisture transfer therethrough and that has a portion of a first major surface coated with a functional layer that comprises a thermoplastic adhesive and a release agent. The release agent operational such that the lid is incompatible at least with conventional shrink wrap film (LDPE) during a conventional heat shrinking process.
摘要:
A container cap for use on a container top. The container cap includes a heat-sealable central portion for securing to the bottle top rim, a peripheral portion integral with the central portion adapted to be formed into a skirt around the neck of the container top, at least one lift tab connected to the peripheral portion, and a predetermined weakened line formed on one of the central or peripheral portions. The weakened line is operatively connected to one or more lift tabs in alternate arrangements.

A coating composition for application to primed metal substrates as a topcoat is disclosed. The coating composition is especially useful on metal closures for vacuum-packed food products. The coating composition is free of a halide-containing vinyl polymer and comprises: (a) an epoxy novolac resin, (b) a phenolic resin, (c) a polyester, and (d) an elastomer, in (e) a nonaqueous carrier.
摘要:
A coating composition that inhibits corrosion of metal substrates, a method of inhibiting corrosion of a metal substrate with a corrosion-inhibiting coating composition, and a metal article that resists corrosion are disclosed. The corrosion-inhibiting coating composition comprises: (a) a high molecular weight epoxy resin; (b) a phenolic resin; (c) an organic corrosion inhibitor having the general structural formula ##STR1## wherein each R is selected, independently, from the group consisting of hydrogen, alkyl, haloalkyl, alkoxy, alkylthio, alkylsulfonyl, cycloalkyl, phenyl, alkylphenyl, phenylalkyl, halo, cyano, nitro, carboxyl, carboxyalkyl, hydroxy, amino, and carbamoyl, and wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are selected, independently, from the group consisting of hydrogen, alkyl, hydroxyalkyl, haloalkyl, alkoxyalkyl, carboxyalkyl, carboxyl, phenyl, and phenylalkyl, and wherein at least one of the R.sub.1, R.sub.2, R.sub.3 and R.sub.4 groups is a carboxyl group; and (d) a suitable nonaqueous carrier.
